Description

TECHNICAL FIELD The present invention relates to a remotely operated drain plug device that opens and closes a drain port of a tank body by operating an operation section provided at a position spaced apart from the drain port.

Conventionally, in order to treat the wastewater generated inside the tank body such as a bathtub or a washbowl, a drainage port is provided at the bottom of the tank body, etc., and the wastewater is discharged from this drain port to the sewer side through a piping member. is widely known. In addition, when water is stored in the tank body, there is a method of opening and closing the drain port by using the lifting and lowering of the lid. A remotely operated drain plug device is known which is operated by operating an operation part provided on the edge of the tank body or on the upper side of the tank body.
As a widely known remote-operated drain plug device, as described in Patent Document 1, a drain port provided on the bottom surface of a tank body, a lid body that closes the drain port by moving up and down, and a tank body and a release wire for transmitting an operation applied to the operation part to a cover provided on the drain port. In the remote-controlled drain plug device described in Patent Document 1, a lock mechanism (thrust lock mechanism) is provided at the end portion of the release wire on the operating portion side in order to maintain the lifted state of the lid. is arranged in a flow path continuing from the drain port by a support member, and is fixedly arranged below the lid.
The lock mechanism consists of a cylindrical lock mechanism body and a lock shaft that advances and retreats in the lock mechanism body, one end of the lock shaft being connected to the inner wire of the release wire and the other end being connected to the operation button. .
Each time the operation button is pressed, the lock mechanism advances the lock shaft and the inner wire connected to the lock shaft toward the drain port, fixes/releases the lock, and moves the lock shaft and the inner wire toward the operation button. Retreat to and repeat alternately. As a result, the inner wire pushes up the lid, and the lid separates from the drain, thereby maintaining the open state of the drain. You can alternately close your mouth.
In this way, by operating the operation unit located away from the drain port, the drain port can be opened and closed by remote control.

Further, in the remote-controlled drain plug device described in Patent Document 1, the operation is performed by pressing the operation button from above to the bottom. A configuration has also been proposed in which the operation buttons are arranged in the horizontal direction and the operation buttons are advanced and retracted in the horizontal direction. If the operation part is arranged at the edge of the opening of the bath body such as a bathtub, the user may feel discomfort or malfunction the remote-controlled drain plug device by accidentally touching the operation part. In addition, there are problems such as inconvenient layout and deterioration of design. Therefore, as in Patent Document 2, a method has been proposed to solve these problems by providing the operating portion in the lateral direction of the tank body.

In the remote control drain plug device, when performing construction or maintenance, a release wire for transmitting the operation applied to the operation part is arranged from the operation part to the vicinity of the cover such as the support member near the drain port. , it may be necessary to perform recovery work after connecting to or conversely removing from related members.
Here, like a remote-controlled drain plug device for a washbasin, the release wire is usually installed above the floor surface, and can be easily moved from the living space to the outside (back side) of the tank body such as the inside of the cabinet. If the tank body has a structure that allows it to come into contact with the , it is relatively easy to connect and remove the release wire during construction and maintenance.
However, in a bathtub, etc., the drain port is located at a position lower than the floor surface, and the release wire is usually installed in a narrow space between the bathtub and the bathtub pan. In order to access the space on the back side, it is necessary to remove large parts such as the apron on the side of the bathtub with difficulty, and furthermore, it is not possible to touch the space on the outside (back side) of the tank body after construction. A remotely operated drain plug device may be employed in the tank body of the structure.
When a remote-controlled drain plug device is used for such a tank body, a tubular guide member such as a hose pipe is used to guide the release wire from the operation part to the vicinity of the drain port without performing work from the outside of the tank body. Know how to guide.
In the case of the remote-controlled drain plug device described in Patent Document 1, a guide member made of a hose tube having flexibility in the lateral direction is connected from the operation part to the joint member connected to the member of the drain port. During construction and maintenance, by passing the release wire through the inside of the guide member from the operation part to the joint member, the release wire can be arranged from the operation part to the drain port without having to work from the outside of the tank body. Then, the release wire can be connected to a related member, or conversely, after being detached from the related member, the release wire can be taken out from the operation portion.
Since the guide member has flexibility in the lateral direction, the guide member can be easily bent and arranged from the operating portion to the joint member during construction.

JP 2013-79490 JP 2014-148831

The tubular body of the guide member is laterally flexible. This is because, as mentioned above, it is necessary to bend the guide member according to the shape of the tank body to be constructed, the arrangement position of the operation part, the drain port, and the joint member. In many cases, a hose pipe made of PVC or the like is used.
Here, as in Patent Document 1, the axial direction of the end portion of the guide member on the operating portion side is oriented in the vertical direction, and while generating an arc of sufficient size, it is bent toward the member of the drain port and oriented in the horizontal direction. When oriented, the path for guiding the release wire formed inside the guide member is not blocked.
However, as in the remote-controlled drain plug device described in Patent Document 2, when the operating portion is provided on the side surface of the tank body and the guide member is connected in the horizontal direction, the guide member 12, the path for guiding the release wire may be blocked at the bent portion. In FIG. 12, the guide member connected to the operation portion extends horizontally from the operation portion, but due to reasons such as the location of the operation portion and the design, the guide member extends upward from the operation portion rather than horizontally. It is possible that Also, even if the angle is gentler than normal, but not vertical, the clogging of the guide member may occur due to bending as described above.

In addition, clogging due to bending occurs not only in the vicinity of the operation portion due to the weight of the guide member itself, but also in the case where the guide member is arranged along the side corner portion of the tank body as shown in FIG. 13, for example. may occur. In the conventional example of FIG. 13, the length of the hose pipe is set on the assumption that the guide member is arranged along the shortest distance indicated by the dotted line. However, due to the weight of the hose pipe, the hose pipe hangs down as shown by the solid line, and the hose pipe may be arranged to pass a longer distance than the shortest distance. In some cases, the guide path is blocked by being crushed by being strongly pressed against the .
The present invention has been made in view of the above problems. To provide a remotely operated drain plug device in which a guide member is not clogged and insertion of a release wire is not hindered.

The present invention according to claim 1 comprises a tank body having a drain port on the bottom surface, a lid body for opening and closing the drain port, an operation unit fixed in the vicinity of the tank body for operating the drain port, and an operation unit.
